SMOKING PIPE.

Specification of Lettersiatent.

1 I Patented Apr.2,1918.

Application filed June 8, 1917. Serial No; 173,537.

To all whom it may concern:

Be it known that I, Josnr r CHAR ns Aoeosrn Lament, a subject ofthe King of Great Britain, residing at 419 Vi'g'e'i" street, in the city of Montreal, in the Province of Quebec, in the Dominion of Canada,

have invented certain new and useful Im- I provements in Smoking-Pipes; and I do hereby declare that the following is a full, clear, and exact description of the same.

The present invention relates to improvements in smoking pipes, to be hereinafter described, and in order to more clearly disclose the construction and operation and use of the invention, reference should be had to the accompanying drawings forming part of the present application. 7

In the drawings, Figure 1 is a longitudinal section through the pipe.

Fig. 2 is a perspective view of the pre ferred form of the battle which comprises the invention, and

Fig. 3 is a side view thereof.

Fig.4 is a longitudinal section through the pipe, showing a modification of the invention.

Throughout the several figures of the drawings, like numerals of reference designate the same parts.

In the drawings, 1 is the bowl of the pipe, having the usual tubular stem section or neck 2, and 3 is the usual tubular stem which engages said neck 2 in any suitable manner, here shown as fitting snugly in said neck 2. 4 is a battle member of unitary construction suitably disposed within the bore of the neck 2 and preferably consists of cylindrical sections 5, 6 and 7 united together by the flat webs 8 and 9, said webs being disposed in a common plane which passes through the axis of the baflie. j

The innermost cylindrical section 5 preferably has a semi-spherical head 10, and the outermost cylindrical section 7 is here illustrated with an inner thread 11 adapted to engage a corresponding thread on the end of the stem 3. The sections 5 and 6 are respectively provided with the channels 12 and 13, while the web 8 is provided with a slot 14. The web 9 consists of two flat members, which are spaced apart to provide an opening or passage between them.

It will thus be seen that the smoke will enter the channel 12, pass through the slot 14, through the channel 13 and in between the two members of the web 9 and into the tubular stem 3. Inso doing, the h'eavier products, such as nicotin, of which the smoke is composed will colitect' in thechambers 15, 16 and 17, and when the smoke reaches the mouth of the smoker it will have been purified and deprived of nicotin. Therefore, the tobacco, which undoubtedly is drawn into the stem in the ordinary pipe, will be held within the compartments 15, 16 and 17 and thus prevented from blocking the stem or reaching the mouth of the smoker.

The neck 2, as illustrated in the drawings,

has been considerably enlarged in order to show the invention properly, but it is thought that the usual tubular opening will have to be very slightly enlarged. Moreover, the improved baffle is here shown as being threaded on the end of the stem 3; but without departing from the spirit of the invention, it will be clearlyseen that it can be made independent therefrom, or instead 'of using a thread, a snug connection would the member 4 is pulled out; but probably in same special pipe designs this would not be practicable, and the stem, therefore, could be made absolutely independent from the member 4.

In cleaning the pipe illustrated in the drawings, all that is necessary to do is to pull out the stem 3 from the neck 2, which removes the baflle member 4 with it, and clean the member 4 by any suitable means. In removing the member 4, all the dirt, nicotin and tobacco in the chambers 15, 16 and 17 will be pulled out at the same time.

The modification illustrated in Fig. 4 differs slightly from the preferred form disclosed in ig. 2 in the flanged end 18 which overlaps the end of the pipe. The stem 3 may be screwed or otherwise secured to said end 18.

What I claim is As a new article of manufacture, a bafile device of unitary construction adapted to fit in the-bore of the neck of a pipe and consisting of a plurality of cylindrical sections arranged in spaced, parallel relation trans- 10 its preriphery, and each Web being provided with a slot, to permit the passage of the smoke therethrough, the outermost section having an axial smoke passage into which the slot in the adjacent web directly opens.

Signed at Montreal, Quebec, Canada, this 15 14th day of April, 1917.
